BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to the field of plant breeding and, more specifically, to the development of tomato varieties Picus, FDS 14-2081 and FDS 14-2090.

The goal of vegetable breeding is to combine various desirable traits in a single variety/hybrid. Such desirable traits may include greater yield, resistance to diseases, insects or other pests, tolerance to heat and drought, better agronomic quality, higher nutritional value, enhanced growth rate and improved fruit properties.

Breeding techniques take advantage of a plant's method of pollination. There are two general methods of pollination: a plant self-pollinates if pollen from one flower is transferred to the same or another flower of the same genotype. A plant cross-pollinates if pollen comes to it from a flower of a different genotype.

Plants that have been self-pollinated and selected for a uniform type over many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny of homozygous plants. A cross between two such homozygous plants of different varieties produces a uniform population of hybrid plants that are heterozygous for many gene loci. The extent of heterozygosity in the hybrid is a function of the genetic distance between the parents. Conversely, a cross of two plants each heterozygous at a number of loci produces a segregating population of hybrid plants that differ genetically and are not uniform. The resulting non-uniformity makes performance unpredictable.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides a tomato plant of the variety designated Picus, or of tomato variety FDS 14-2081 or FDS 14-2090. Also provided are tomato plants having all the physiological and morphological characteristics of such plants. Parts of the tomato plant of the present invention are also provided, for example, including pollen, an ovule, a fruit, a scion, a rootstock and a cell of the plant.

The invention also concerns seed of tomato variety Picus, tomato variety FDS 14-2081 and tomato variety FDS 14-2090. The tomato seed of the invention may be provided as an essentially homogeneous population of tomato seed. Therefore, seed of the invention may be defined as forming at least about 97% of the total seed, including at least about 98%, 99% or more of the seed. The population of tomato seed may be particularly defined as being essentially free from hybrid seed. The seed population may be separately grown to provide an essentially homogeneous population of tomato plants according to the invention.

In another aspect of the invention, a tissue culture of regenerable cells of a plant of variety Picus or tomato variety FDS 14-2081 or FDS 14-2090 is provided. The tissue culture will preferably be capable of regenerating plants capable of expressing all of the physiological and morphological characteristics of a plant of the invention, and of regenerating plants having substantially the same genotype as other such plants. Examples of some such physiological and morphological characteristics include those traits set forth in the tables herein. The regenerable cells in such tissue cultures may be derived, for example, from embryos, meristems, cotyledons, pollen, leaves, anthers, roots, root tips, pistil, flower, seed and stalks. Still further, the present invention provides tomato plants regenerated from a tissue culture of the invention, the plants having all the physiological and morphological characteristics of a plant of the invention.

In yet another aspect of the invention, processes are provided for producing tomato seeds, plants and fruit, which processes generally comprise crossing a first parent tomato plant with a second parent tomato plant, wherein at least one of the first or second parent tomato plants is a plant of the of the variety designated Picus, or of tomato variety FDS 14-2081 or FDS 14-2090. These processes may be further exemplified as processes for preparing hybrid tomato seed or plants, wherein a first tomato plant is crossed with a second tomato plant of a different, distinct variety to provide a hybrid that has, as one of its parents, the tomato plant variety FDS 14-2081 or FDS 14-2090. In one embodiment of the invention, tomato varieties FDS 14-2081 and FDS 14-2090 are crossed to produce hybrid seed of the variety designated Picus. In any cross herein, either parent may be the male or female parent. In these processes, crossing will result in the production of seed. The seed production occurs regardless of whether the seed is collected or not.

In one embodiment of the invention, the first step in “crossing” comprises planting seeds of a first and second parent tomato plant, often in proximity so that pollination will occur for example, mediated by insect vectors. Alternatively, pollen can be transferred manually. Where the plant is self-pollinated, pollination may occur without the need for direct human intervention other than plant cultivation.

A second step may comprise cultivating or growing the seeds of first and second parent tomato plants into plants that bear flowers. A third step may comprise preventing self-pollination of the plants, such as by emasculating the male portions of flowers, (e.g., treating or manipulating the flowers to produce an emasculated parent tomato plant). Self-incompatibility systems may also be used in some hybrid crops for the same purpose. Self-incompatible plants still shed viable pollen and can pollinate plants of other varieties but are incapable of pollinating themselves or other plants of the same variety.

A fourth step for a hybrid cross may comprise cross-pollination between the first and second parent tomato plants. In certain embodiments, pollen may be transferred manually or by the use of insect vectors. Yet another step comprises harvesting the seeds from at least one of the parent tomato plants. The harvested seed can be grown to produce a tomato plant or hybrid tomato plant.

The present invention also provides the tomato seeds and plants produced by a process that comprises crossing a first parent tomato plant with a second parent tomato plant, wherein at least one of the first or second parent tomato plants is a plant provided herein, such as from variety Picus, tomato variety FDS 14-2081 and tomato variety FDS 14-2090. In another embodiment of the invention, tomato seed and plants produced by the process are first filial generation (F₁) hybrid tomato seed and plants produced by crossing a plant in accordance with the invention with another, distinct plant. The present invention further contemplates plant parts of such an F₁ hybrid tomato plant, and methods of use thereof. Therefore, certain exemplary embodiments of the invention provide an F₁ hybrid tomato plant and seed thereof.

In still yet another aspect, the present invention provides a method of producing a plant or a seed derived from one or more of variety Picus, tomato variety FDS 14-2081 and tomato variety FDS 14-2090, method comprising the steps of: (a) preparing a progeny plant derived from said variety by crossing a plant of variety Picus, tomato variety FDS 14-2081 or tomato variety FDS 14-2090, with a second plant; and (b) selfing the progeny plant or crossing it to the second plant or to a third plant to produce a seed of a progeny plant of a subsequent generation.

The method may additionally comprise: (c) growing a progeny plant of a subsequent generation from said seed of a progeny plant of a subsequent generation and selfing the progeny plant of a subsequent generation or crossing it to the second, the third, or a further plant; and repeating the steps for an additional 3-10 generations to produce a further plant derived from the aforementioned starting variety. The further plant derived from variety Picus, variety FDS 14-2081 or variety FDS 14-2090 may be an inbred variety, and the aforementioned repeated crossing steps may be defined as comprising sufficient inbreeding to produce the inbred variety. In the method, it may be desirable to select particular plants resulting from step (c) for continued crossing according to steps (b) and (c). By selecting plants having one or more desirable traits, a plant is obtained which possesses some of the desirable traits of the starting plant as well as potentially other selected traits.

The invention also concerns methods of vegetatively propagating a plant of the invention. In certain embodiments, the method comprises the steps of: (a) collecting tissue capable of being propagated from a plant of the invention; (b) cultivating said tissue to obtain proliferated shoots; and (c) rooting said proliferated shoots to obtain rooted plantlets. In some of these embodiments, the method further comprises growing plants from said rooted plantlets.

In another aspect of the invention, a plant of variety Picus, variety FDS 14-2081 or variety FDS 14-2090 comprising an added heritable trait is provided. The heritable trait may comprise a genetic locus that is, for example, a dominant or recessive allele. In one embodiment of the invention, a plant of the invention is defined as comprising a single locus conversion. For example, one or more heritable traits may be introgressed at any particular locus using a different allele that confers the new trait or traits of interest. In specific embodiments of the invention, the single locus conversion confers one or more traits such as, for example, herbicide tolerance, insect resistance, disease resistance and modulation of plant metabolism and metabolite profiles. In further embodiments, the trait may be conferred by a naturally occurring gene introduced into the genome of the variety by backcrossing, a natural or induced mutation, or a transgene introduced through genetic transformation techniques into the plant or a progenitor of any previous generation thereof. When introduced through transformation, a genetic locus may comprise one or more genes integrated at a single chromosomal location.

For example, in certain embodiments, the invention provides methods of introducing a desired trait into a plant of the invention comprising: (a) crossing a plant of variety Picus, variety FDS 14-2081 or variety FDS 14-2090 with a second tomato plant that comprises a desired trait to produce F1 progeny, (b) selecting an F1 progeny that comprises the desired trait, (c) crossing the selected F1 progeny with a plant of variety Picus, variety FDS 14-2081 or variety FDS 14-2090 to produce backcross progeny, and (d) selecting backcross progeny comprising the desired trait and the physiological and morphological characteristic of variety Picus, variety FDS 14-2081 or variety FDS 14-2090. The invention also provides tomato plants produced by these methods.

In still yet another aspect of the invention, the genetic complement of a tomato plant variety of the invention. The phrase “genetic complement” is used to refer to the aggregate of nucleotide sequences, the expression of which defines the phenotype of, in the present case, a tomato plant of, or a cell or tissue of that plant. A genetic complement thus represents the genetic makeup of a cell, tissue or plant, and a hybrid genetic complement represents the genetic make up of a hybrid cell, tissue or plant. The invention thus provides tomato plant cells that have a genetic complement in accordance with the tomato plant cells disclosed herein, and plants, seeds and plants containing such cells.

Plant genetic complements may be assessed by genetic marker profiles, and by the expression of phenotypic traits that are characteristic of the expression of the genetic complement, e.g., gene expression profiles, gene product expression profiles and isozyme typing profiles. It is understood that a plant of the invention or a first generation progeny thereof could be identified by any of the many well known techniques such as, for example, Simple Sequence Length Polymorphisms (SSLPs) (Williams et al., 1990), Randomly Amplified Polymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858, specifically incorporated herein by reference in its entirety), and Single Nucleotide Polymorphisms (SNPs) (Wang et al., 1998).

In still yet another aspect, the present invention provides hybrid genetic complements, as represented by tomato plant cells, tissues, plants, and seeds, formed by the combination of a haploid genetic complement of a tomato plant of the invention with a haploid genetic complement of a second tomato plant, preferably, another, distinct tomato plant. In another aspect, the present invention provides a tomato plant regenerated from a tissue culture that comprises a hybrid genetic complement of this invention.

In still yet another aspect, the invention provides a plant of an inbred tomato variety that exhibits a combination of traits comprising a broad adaptability from Florida to Wisconsin, production of an excellent set of uniformly shaped fruit, and resistance to Alternaria alternata f. sp. lycopersici, Fusarium oxysporum f. sp. lycopersici race 1 and race 2, Stemphylium solani, Verticillium albo-atrum race 1, and Tomato Spotted Wilt Virus. In certain embodiments, the combination of traits may be defined as controlled by genetic means for the expression of the combination of traits found in tomato variety Picus.

In still yet another aspect, the invention provides a method of determining the genotype of a plant of the invention comprising detecting in the genome of the plant at least a first polymorphism. The method may, in certain embodiments, comprise detecting a plurality of polymorphisms in the genome of the plant. The method may further comprise storing the results of the step of detecting the plurality of polymorphisms on a computer readable medium. The invention further provides a computer readable medium produced by such a method.

In certain embodiments, the present invention provides a method of producing tomatoes comprising: (a) obtaining a plant of the invention, wherein the plant has been cultivated to maturity, and (b) collecting tomatoes from the plant.

Any embodiment discussed herein with respect to one aspect of the invention applies to other aspects of the invention as well, unless specifically noted.

The term “about” is used to indicate that a value includes the standard deviation of error for the device or method being employed to determine the value. The use of the term “or” in the claims is used to mean “and/or” unless explicitly indicated to refer to alternatives only or the alternatives are mutually exclusive, although the disclosure supports a definition that refers to only alternatives and to “and/or.” When used in conjunction with the word “comprising” or other open language in the claims, the words “a” and “an” denote “one or more,” unless specifically noted.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides methods and compositions relating to plants, plant parts, seeds and derivatives of tomato variety Picus, as well as parent plants capable of being crossed to produce this variety, designated variety FDS 14-2081 and variety FDS 14-2090. Picus is an F1 hybrid Saladette tomato. These plants show genetic uniformity and stability and horticultural uniformity and stability within the limits of environmental influence for the traits described hereinafter. The plants provide sufficient seed yield. By crossing with a distinct second plant, uniform F1 hybrid progeny can be obtained.

Variety Picus exhibits a number of improved traits including its broad adaptability from Florida to Wisconsin and its production of an excellent set of uniformly shaped fruit. In addition, the Picus variety is resistant to Alternaria alternata f. sp. lycopersici, Fusarium oxysporum f. sp. lycopersici races 1 and 2, Stemphylium solani, Verticillium albo-atrum race 1, and Tomato Spotted Wilt Virus. The development of the variety can be summarized as follows. The parents of Picus are particularly useful for the production of hybrid varieties based on the beneficial traits conferred in hybrid combination.

A. Origin and Breeding History of Tomato Variety Picus

The tomato variety Picus was made by crossing FDS 14-2081 with FDS 14-2090. In one embodiment, Picus is produced by a cross between FDS 14-2081 as the seed parent and FDS 14-2090 as the pollen parent. The breeding objective was to develop a determinate tomato inbred variety with uniform size and good combining ability to be used in the development of hybrid cultivars for the saladette tomato category.

The breeding objective of FDS 14-2090 was the development of the variety with a determinate tomato with uniform size and good combining ability to be used in the development of hybrid cultivars for the saladette tomato category. As is true with other tomato varieties, a small percentage of variants can occur within commercially acceptable limits for almost any characteristic during the course of repeated multiplication. However no variants were observed during the two years in which the variety was observed to be uniform and stable.

B. Physiological and Morphological Characteristics of Tomato Variety Picus

Tomato cultivars may be grouped by maturity, i.e. the time required from planting the seed to the stage where fruit harvest can occur. Standard maturity classifications include ‘early’, ‘midseason’ or ‘late-maturing’. Another classification for tomatoes is the developmental timing of fruit set. ‘Determinant’ plants grow foliage, then transition into a reproductive phase of flower setting, pollination and fruit development. Consequently, determinant cultivars have a large proportion of the fruit ripen within a short time frame. Growers that harvest only once in a season favor determinant type cultivars. In contrast, ‘indeterminate’ types grow foliage, then enter a long phase where flower and fruit development proceed along with new foliar growth. Growers that harvest the same plants multiple times favor indeterminate type cultivars. In response to more recent consumer demands for dietary diversity, tomato breeders have developed a wider range of colors. In addition to expanding the range of red colored fruits, there are cultivars that produce fruits that are creamy white, lime green, yellow, green, golden, orange and purple. Additionally, there are multi-colored varieties exemplified by mainly red fruited varieties with green shoulders, and both striped- and variegated-colored fruit. Standard methods for determining tomato fruit color are described, for instance, in Gull et al. (1989) and Kader et al. (1978), both of which are incorporated by reference herein.

In accordance with one aspect of the present invention, there is provided a plant having the physiological and morphological characteristics of tomato variety Picus. A description of the physiological and morphological characteristics of tomato variety Picus is presented in Table 1.

Values may vary due to environment. Other values that are substantially equivalent are also within the scope of the invention.

Variety Picus has been self-pollinated and planted for a number of generations to produce the homozygosity and phenotypic stability to make this variety useful in commercial seed production. No variant traits have been observed or are expected for this variety.

Tomato variety Picus, being substantially homozygous, can be reproduced by planting seeds of the variety, growing the resulting tomato plant under self-pollinating or sib-pollinating conditions and harvesting the resulting seeds using techniques familiar to one of skill in the art.

As described above, variety Picus exhibits desirable agronomic traits, including its broad adaptability from Florida to Wisconsin, and its production of an excellent set of uniformly shaped fruit. In addition, the Picus variety is resistant to Alternaria alternata f.sp. lycopersici, Fusarium oxysporum f.sp. lycopersici races 1 and 2, Stemphylium solani, Verticillium albo-atrum race 1, and Tomato Spotted Wilt Virus. As shown above, variety Picus exhibits superior characteristics when compared to competing varieties. For example, Picus, which is a fresh market saladette tomato hybrid similar in fruit shape to the Sunoma, has resistance to Tomato Spotted Wilt Virus whereas Sunoma lacks this resistance.

C. Development of Tomato Variety FDS 14-2081

The hybrid Picus was developed as a cross of FDS 14-2081 and FDS 14-2090, frequently with FDS 14-2081 used as the female.

D. Breeding of Tomato Plants of the Invention

One aspect of the current invention concerns methods for crossing a tomato variety provided herein with itself or a second plant and the seeds and plants produced by such methods. These methods can be used for propagation of a variety provided herein, or can be used to produce hybrid tomato seeds and the plants grown therefrom. Such hybrid seeds can be produced by crossing the parent varieties of the variety.

The development of new varieties using one or more starting varieties is well known in the art. In accordance with the invention, novel varieties may be created by crossing a plant of the invention followed by multiple generations of breeding according to such well known methods. New varieties may be created by crossing with any second plant. In selecting such a second plant to cross for the purpose of developing novel varieties, it may be desired to choose those plants that either themselves exhibit one or more selected desirable characteristics or that exhibit the desired characteristic(s) when in hybrid combination. Once initial crosses have been made, inbreeding and selection take place to produce new varieties. For development of a uniform variety, often five or more generations of selfing and selection are involved.

Uniform varieties of new varieties may also be developed by way of double-haploids. This technique allows the creation of true breeding varieties without the need for multiple generations of selfing and selection. In this manner, true breeding varieties can be produced in as little as one generation. Haploid embryos may be produced from microspores, pollen, anther cultures, or ovary cultures. The haploid embryos may then be doubled autonomously, or by chemical treatments (e.g. colchicine treatment). Alternatively, haploid embryos may be grown into haploid plants and treated to induce chromosome doubling. In either case, fertile homozygous plants are obtained. In accordance with the invention, any of such techniques may be used in connection with a plant of the invention and progeny thereof to achieve a homozygous variety.

Backcrossing can also be used to improve an inbred plant. Backcrossing transfers one or more heritable traits from one inbred or non-inbred source to an inbred that lacks those traits. The exact backcrossing protocol will depend on the characteristic(s) or trait(s) being altered to determine an appropriate testing protocol. When the term variety Picus, variety FDS 14-2081 or variety FDS 14-2090 is used in the context of the present invention, this also includes plants modified to include at least a first desired heritable trait.

This can be accomplished, for example, by first crossing a superior inbred (recurrent parent) to a donor inbred (non-recurrent parent), which carries the appropriate genetic information (e.g., an allele) at the locus or loci relevant to the trait in question. The progeny of this cross are then mated back to the recurrent parent followed by selection in the resultant progeny (first backcross generation, or BC1) for the desired trait to be transferred from the non-recurrent parent. After five or more backcross generations with selection for the desired trait, the progeny are heterozygous at loci controlling the characteristic being transferred, but are like the superior parent for most or almost all other loci. The last backcross generation would be selfed to give pure breeding progeny for the trait being transferred.

The parental tomato plant which contributes the desired characteristic or characteristics is termed the non-recurrent parent because it can be used one time in the backcross protocol and therefore need not recur. The parental tomato plant to which the locus or loci from the non-recurrent parent are transferred is known as the recurrent parent as it is used for several rounds in the backcrossing protocol.

Many single locus traits have been identified that are not regularly selected for in the development of a new inbred but that can be improved by backcrossing techniques. Single locus traits may or may not be transgenic; examples of these traits include, but are not limited to, male sterility, herbicide resistance, resistance to bacterial, fungal, or viral disease, insect resistance, restoration of male fertility, modified fatty acid or carbohydrate metabolism, and enhanced nutritional quality. These comprise genes generally inherited through the nucleus.

Direct selection or screening may be applied where the single locus (e.g. allele) acts in a dominant fashion. For example, when selecting for a dominant allele providing resistance to a bacterial disease, the progeny of the initial cross can be inoculated with bacteria prior to the backcrossing. The inoculation then eliminates those plants which do not have the resistance, and only those plants which have the resistance allele are used in the subsequent backcross. This process is then repeated for all additional backcross generations.

Although backcrossing methods are simplified when the characteristic being transferred is a dominant allele, recessive, co-dominant and quantitative alleles may also be transferred. In this instance, it may be necessary to introduce a test of the progeny to determine if the desired locus has been successfully transferred. In the case where the non-recurrent variety was not homozygous, the F1 progeny would not be equivalent. F1 plants having the desired genotype at the locus of interest could be phenotypically selected if the corresponding trait was phenotypically detectable in a heterozygous or hemizygous state. In the case where a recessive allele is to be transferred and the corresponding trait is not phenotypically detectable in the heterozygous of hemizygous state, the resultant progeny can be selfed, or crossed back to the donor to create a segregating population for selection purposes. Non-phenotypic tests may also be employed. Selected progeny from the segregating population can then be crossed to the recurrent parent to make the first backcross generation (BC1).

Molecular markers may also be used to aid in the identification of the plants containing both a desired trait and having recovered a high percentage of the recurrent parent's genetic complement. Selection of tomato plants for breeding is not necessarily dependent on the phenotype of a plant and instead can be based on genetic investigations. For example, one can utilize a suitable genetic marker which is closely genetically linked to a trait of interest. One of these markers can be used to identify the presence or absence of a trait in the offspring of a particular cross, and can be used in selection of progeny for continued breeding. This technique is commonly referred to as marker assisted selection. Any other type of genetic marker or other assay that is able to identify the relative presence or absence of a trait of interest in a plant can also be useful for breeding purposes. Procedures for marker assisted selection applicable to the breeding of tomato are well known in the art. Such methods will be of particular utility in the case of recessive traits and variable phenotypes, or where conventional assays may be more expensive, time consuming or otherwise disadvantageous. Types of genetic markers which could be used in accordance with the invention include, but are not necessarily limited to, Simple Sequence Length Polymorphisms (SSLPs) (Williams et al., 1990), Simple Sequence Repeats (SSR), Randomly Amplified Polymorphic DNAs (RAPDs), DNA Amplification Fingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs), Arbitrary Primed Polymerase Chain Reaction (AP-PCR), Amplified Fragment Length Polymorphisms (AFLPs) (EP 534 858, specifically incorporated herein by reference in its entirety), and Single Nucleotide Polymorphisms (SNPs) (Wang et al., 1998).

Tomato varieties can also be developed from more than two parents. The technique, known as modified backcrossing, uses different recurrent parents during the backcrossing. Modified backcrossing may be used to replace the original recurrent parent with a variety having certain more desirable characteristics or multiple parents may be used to obtain different desirable characteristics from each.

Tomatoes are grown for use as rootstocks or scions. Typically, different types of tomatoes are grafted to enhance disease resistance, which is usually conferred by the rootstock, while retaining the horticultural qualities usually conferred by the scion. It is not uncommon for grafting to occur between Solanum lycopersicum varieties and related Solanum species. Methods of grafting and vegetative propagation are well-known in the art.

The varieties and varieties of the present invention are particularly well suited for the development of new varieties or varieties based on the elite nature of the genetic background of the variety. In selecting a second plant to cross with Picus, variety FDS 14-2081 or variety FDS 14-2090 for the purpose of developing novel tomato varieties, it will typically be preferred to choose those plants that either themselves exhibit one or more selected desirable characteristics or that exhibit the desired characteristic(s) when in hybrid combination. Examples of desirable characteristics may include, but are not limited to herbicide tolerance, pathogen resistance (e.g., insect resistance, nematode resistance, resistance to bacterial, fungal, and viral disease), male fertility, improved harvest characteristics, enhanced nutritional quality, increased antioxidant content, improved processing characteristics, high yield, improved characteristics related to the fruit flavor, texture, size, shape, durability, shelf life, and yield, improved vine habit, increased soluble solids content, uniform ripening, delayed or early ripening, reduced blossom end scar size, seedling vigor, adaptability for soil conditions, and adaptability for climate conditions. Qualities that may be desirable in a processing tomato are not necessarily those that would be desirable in a fresh market tomato; thus, the selection process for desirable traits for each specific end use may be different. For example, certain features, such as solids content, and firm fruit to facilitate mechanical harvesting are more desirable in the development of processing tomatoes; whereas, external features such as intensity and uniformity of fruit color, unblemished fruit, and uniform fruit size are typically more important to the development of a fresh market product that will have greater retailer or consumer appeal. Of course, certain traits, such as disease and pest resistance, high yield, and concentrated fruit set are of interest in any type of tomato variety or variety.

E. Plants of the Invention Derived by Genetic Engineering

Many useful traits that can be introduced by backcrossing, as well as directly into a plant, are those that are introduced by genetic transformation techniques. Genetic transformation may therefore be used to insert a selected transgene into the tomato variety of the invention or may, alternatively, be used for the preparation of varieties containing transgenes that can be subsequently transferred to the variety of interest by crossing. Methods for the transformation of plants, including tomato, are well known to those of skill in the art. Techniques which may be employed for the genetic transformation of tomato include, but are not limited to, electroporation, microprojectile bombardment, Agrobacterium-mediated transformation, pollen-mediated transformation, and direct DNA uptake by protoplasts.

To effect transformation by electroporation, one may employ either friable tissues, such as a suspension culture of cells or embryogenic callus or alternatively one may transform immature embryos or other organized tissue directly. In this technique, one would partially degrade the cell walls of the chosen cells by exposing them to pectin-degrading enzymes (pectolyases) or mechanically wound tissues in a controlled manner.

To effect pollen-mediated transformation, one may apply pollen pretreated with DNA to the female reproduction parts of tomato plants for pollination. A pollen-mediated method for the transformation of tomato is disclosed in U.S. Pat. No. 6,806,399.

A particularly efficient method for delivering transforming DNA segments to plant cells is microprojectile bombardment. In this method, particles are coated with nucleic acids and delivered into cells by a propelling force. Exemplary particles include those comprised of tungsten, platinum, and preferably, gold. For the bombardment, cells in suspension are concentrated on filters or solid culture medium. Alternatively, immature embryos or other target cells may be arranged on solid culture medium. The cells to be bombarded are positioned at an appropriate distance below the macroprojectile stopping plate.

An illustrative embodiment of a method for delivering DNA into plant cells by acceleration is the Biolistics Particle Delivery System, which can be used to propel particles coated with DNA or cells through a screen, such as a stainless steel or Nytex screen, onto a surface covered with target tomato cells. The screen disperses the particles so that they are not delivered to the recipient cells in large aggregates. It is believed that a screen intervening between the projectile apparatus and the cells to be bombarded reduces the size of projectiles aggregate and may contribute to a higher frequency of transformation by reducing the damage inflicted on the recipient cells by projectiles that are too large.

Microprojectile bombardment techniques are widely applicable, and may be used to transform virtually any plant species.

Agrobacterium-mediated transfer is another widely applicable system for introducing gene loci into plant cells. An advantage of the technique is that DNA can be introduced into whole plant tissues, thereby bypassing the need for regeneration of an intact plant from a protoplast. Modern Agrobacterium transformation vectors are capable of replication in E. coli as well as Agrobacterium, allowing for convenient manipulations (Klee et al., 1985). Moreover, recent technological advances in vectors for Agrobacterium-mediated gene transfer have improved the arrangement of genes and restriction sites in the vectors to facilitate the construction of vectors capable of expressing various polypeptide coding genes. The vectors described have convenient multi-linker regions flanked by a promoter and a polyadenylation site for direct expression of inserted polypeptide coding genes. Additionally, Agrobacterium containing both armed and disarmed Ti genes can be used for transformation.

In those plant species where Agrobacterium-mediated transformation is efficient, it is the method of choice because of the facile and defined nature of the gene locus transfer. The use of Agrobacterium-mediated plant integrating vectors to introduce DNA into plant cells is well known in the art (Fraley et al., 1985; U.S. Pat. No. 5,563,055).

Transformation of plant protoplasts also can be achieved using methods based on calcium phosphate precipitation, polyethylene glycol treatment, electroporation, and combinations of these treatments (see, e.g., Potrykus et al., 1985; Omirulleh et al., 1993; Fromm et al., 1986; Uchimiya et al., 1986; Marcotte et al., 1988). Transformation of plants and expression of foreign genetic elements is exemplified in Choi et al. (1994), and Ellul et al. (2003).

A number of promoters have utility for plant gene expression for any gene of interest including but not limited to selectable markers, scoreable markers, genes for pest tolerance, disease resistance, nutritional enhancements and any other gene of agronomic interest. Examples of constitutive promoters useful for tomato plant gene expression include, but are not limited to, the cauliflower mosaic virus (CaMV) P-35S promoter, which confers constitutive, high-level expression in most plant tissues (see, e.g., Odel et al., 1985), including monocots (see, e.g., Dekeyser et al., 1990; Terada and Shimamoto, 1990); a tandemly, partially duplicated version of the CaMV 35S promoter, the enhanced 35S promoter (P-e35S) the nopaline synthase promoter (An et al., 1988), the octopine synthase promoter (Fromm et al., 1989); and the figwort mosaic virus (P-FMV) promoter as described in U.S. Pat. No. 5,378,619 and an enhanced version of the FMV promoter (P-eFMV) where the promoter sequence of P-FMV is duplicated in tandem, the cauliflower mosaic virus 19S promoter, a sugarcane bacilliform virus promoter, a commelina yellow mottle virus promoter, and other plant DNA virus promoters known to express in plant cells.

A variety of plant gene promoters that are regulated in response to environmental, hormonal, chemical, and/or developmental signals can be used for expression of an operably linked gene in plant cells, including promoters regulated by (1) heat (Callis et al., 1988), (2) light (e.g., pea rbcS-3A promoter, Kuhlemeier et al., 1989; maize rbcS promoter, Schaffner and Sheen, 1991; or chlorophyll a/b-binding protein promoter, Simpson et al., 1985), (3) hormones, such as abscisic acid (Marcotte et al., 1989), (4) wounding (e.g., wunl, Siebertz et al., 1989); or (5) chemicals such as methyl jasmonate, salicylic acid, or Safener. It may also be advantageous to employ organ-specific promoters (e.g., Roshal et al., 1987; Schernthaner et al., 1988; Bustos et al., 1989).

Exemplary nucleic acids which may be introduced to the tomato varieties of this invention include, for example, DNA sequences or genes from another species, or even genes or sequences which originate with or are present in the same species, but are incorporated into recipient cells by genetic engineering methods rather than classical reproduction or breeding techniques. However, the term “exogenous” is also intended to refer to genes that are not normally present in the cell being transformed, or perhaps simply not present in the form, structure, etc., as found in the transforming DNA segment or gene, or genes which are normally present and that one desires to express in a manner that differs from the natural expression pattern, e.g., to over-express. Thus, the term “exogenous” gene or DNA is intended to refer to any gene or DNA segment that is introduced into a recipient cell, regardless of whether a similar gene may already be present in such a cell. The type of DNA included in the exogenous DNA can include DNA which is already present in the plant cell, DNA from another plant, DNA from a different organism, or a DNA generated externally, such as a DNA sequence containing an antisense message of a gene, or a DNA sequence encoding a synthetic or modified version of a gene.

Many hundreds if not thousands of different genes are known and could potentially be introduced into a tomato plant according to the invention. Non-limiting examples of particular genes and corresponding phenotypes one may choose to introduce into a tomato plant include one or more genes for insect tolerance, such as a Bacillus thuringiensis (B.t.) gene, pest tolerance such as genes for fungal disease control, herbicide tolerance such as genes conferring glyphosate tolerance, and genes for quality improvements such as yield, nutritional enhancements, environmental or stress tolerances, or any desirable changes in plant physiology, growth, development, morphology or plant product(s). For example, structural genes would include any gene that confers insect tolerance including but not limited to a Bacillus insect control protein gene as described in WO 99/31248, herein incorporated by reference in its entirety, U.S. Pat. No. 5,689,052, herein incorporated by reference in its entirety, U.S. Pat. Nos. 5,500,365 and 5,880275, herein incorporated by reference it their entirety. In another embodiment, the structural gene can confer tolerance to the herbicide glyphosate as conferred by genes including, but not limited to Agrobacterium strain CP4 glyphosate resistant EPSPS gene (aroA:CP4) as described in U.S. Pat. No. 5,633,435, herein incorporated by reference in its entirety, or glyphosate oxidoreductase gene (GOX) as described in U.S. Pat. No. 5,463,175, herein incorporated by reference in its entirety.

Alternatively, the DNA coding sequences can affect these phenotypes by encoding a non-translatable RNA molecule that causes the targeted inhibition of expression of an endogenous gene, for example via antisense- or cosuppression-mediated mechanisms (see, for example, Bird et al., 1991). The RNA could also be a catalytic RNA molecule (e.g., a ribozyme) engineered to cleave a desired endogenous mRNA product (see for example, Gibson and Shillito, 1997). Thus, any gene which produces a protein or mRNA which expresses a phenotype or morphology change of interest is useful for the practice of the present invention.
